RADIATOR-MOUNTING FOR MOTOR-DRIVEN VEHICLES.

Specification of Letters Patent.

Patented Dec. '7, 1920.

Application filed January 19, 1920. Serial No. 352,292.

To all whom it'may concern:

Be it known that 1, PETER JOHNSON, a citizen of the United States, residing at Stoughton, county of Dane, and State of Wisconsin, have invented new and useful Improvements in Radiator -Mount1ngs for hilotor-Driven Vehicles, of which the following is a specification.

My invention relates to improvements in radiator mountings for motor driven vehicles. I

The object of my invention is to provide a resilient mounting for aradiator which. will support it with the requisite stability and in such a manner as to prevent noise and vibration against associated parts while yielding suficiently to relieve the radiator from destructive strains due to weaving or twisting movements of the main frame. Also to provide a resilient mounting which may be superposed longitudinally on the side bars of the main frame in such a manner as to avoid lateral projections and reduce to a minimum the structural modifications required to apply the mounting to vehicles of ordinary types. 1

In the drawing- Figure 1 is a side elevation of my improved radiator mounting showing the radiator and portions of a motor driven vehicle associated therewith.

Fig. 2 is a fragmentary front elevation of the radiator and its mountings, the supporting frame bars being shown in crosssection.

The side bars 1 of the main frame are supported from the vehicle springs 2 in any ordinary manner, but the radiator 3 is supported from the main frame by longitudinally disposed leaf springs 4. The rear ends of these springs 4 are clamped to or connected with the respective side bars 1 b bolts 5 and are preferably spaced therefrom by spacing blocks 6 (one on each side) and a series of short or reinforcing resilient leaves 7. The bolts 5 pass through the reinforcing leaves and spacing blocks at each side of the hood.

The side members or walls of the radiator frame are provided with laterally projecting brackets composed of horizontal flanges braced by upwardly tapering side flanges 10. Bolts 11 connect the flanges 9 directly to the forwardly projecting ends of the '3 main leaves 4, these leaves being thus utilized to support the radiator resiliently from the main frame or its side bars 1.

The main leaves being reinforced, it is obvious that they may be made sufiiciently rigid to hold the radiator in a substantially fixed relation to the main frame under ordinary conditions of smooth road travel, but the resilience is sufficient to relieve the radiator from excessive strains or shocks, and particularly from torsional strains when the wheels pass into holes or over obstructions. The flat straight leaves also make it possible to superpose them upon the side bars of the main frame in such a manner as to avoid any lateral projections, such as would diminish the radiator receiving space, or, if outwardly extended, would require a special fender structure.

In the construction illustrated, the hood lids 12 are connected by the fastenings 13 with a metal plate 14 which is bolted to a spacing block 15 and to the main frame bar 1 at each side of the vehicle. Each plate 14' projects forwardly over the rear portion of the associated radiator supporting spring, and provides means for clamping the hood lid down at points directly over the set of superposed leaves of the radiator supporting springs as shown in the drawing. The spacing block is formed to provide suflicient clearance between the plate 11 and the spring to allow the necessary movement of the latter. The radiator is wholly supported by the above described springs, ex cept as to the flexible connections of the water circulatory system and the tie rods usually employed to connect the upper portion of the radiator with the body at the sides or above the engine. These water connections and tie rods are of ordinary construction and it being manifest that they would not interfere with the desired independently yielding movements of the radiator, further illustration or description is deemed unnecessary.

With my improved radiator mounting, it is obvious thatthe radiator structure will be relieved of destructive weaving or twisting strains such as the main frame is subjected to in passing over irregular road surfaces or obliquely across gutters and ditches although in all other particulars, and for all other purposes, the mounting conforms substantially to ordinary practice, and therefore no expensive structural alterations in the vehicle are necessary in order to embody my invention therein.

I prefer to employ main leaves having sufficlent normal resiliency to absorb ordinary shocks, without allowing the radiator to shift materially from its normal position or to change its position relatively to the as sociated head margins. This allows what may be described as a normal quivering vibration in a vertical plane, the position of the.- leaves in horizontal planes preventing lateral movements. The abnormal weaving movementsof the mainframe, above referred to, are' absorbednot only by the mainleaves but by the reinforcinglcaves, which operate with progressively increasing resistance to prevent excessive displacement of the radiator structure. while allowing it to. tilt without distortion or destructive strain.
